This invention relates to double-barrel guns, having two triggers, one to fire one barrel and the other trigger the other barrel.

The main object of the-present invention is to provide an improved arrangement whereby, after either barrel has been fired the remaining barrel can be fired by either trigger. the tiring of the remaining barrel being however prevented until after the into voluntary pull due to the firing of the first barrel has taken place.

The invention is illustrated in the accompanying drawings in which Figures 1-5 are sectional elevations showing the parts of the trigger mechanism in differentpositions, Figure 6 a plan view of Figure 1 and Figure 7 a perspective view showing the parts in the position in which they are shown in Figure 1 except that the safety catch is in operative position. Figures 8 and 9 are respectively detail elevation and sectional plan.

1 is a slide mounted on the strap 1' of the gun and having fast on it a pin 2 which passes transversely through the slide 1 so as to projeeton each side thereof. The forward end of the slide is engaged by the forked end of a lever 3 pivotally mounted at 4 on the rear of the action body 5, and urged by a spring 6 to draw the slide 1 forwardly.

The usual barrel locking bolt 7 is so arranged that, when a top lever 8 is moved to break the gun, the bolt 7 comes into contact with the forked lever 3 (see Figure 1) and rocks it. thus moving the slide rearwardly. The slide 1 passes through an aperture formed in a bracket 9 which is integral with the strap 1' and to which a pair of trigger blades or webs 10, 11 is pivoted. The bracket 9 has also pivoted toit a spring pressed pawl 12 which can engage two bent notches or teeth 13, 14 formed in the upper surface of. the slide 1. The pawl 12 is provided on each side with a'lug or projection 15, 16 which presses upon the upper edge of the trigger blades, the spring 17 which acts upon the pawl thus serving as a trigger spring. 7

Each trigger blade is provided with a slot 1S. the bottom of which has two upwardly curved portions or cam surfaces forming frictional stops 19, 20 which, when the t ig,

ger is pulled, are moved into the path of the pin 2 on the slide 1, as will be described later.

Each trigger blade is also provided at the rear with a recess 21 adapted to be engaged by one of a pair of projections or lugs 22 on. the end of a lever 23 pivotally mount-ed on the read end of the slide 1. The lever is urged by a spring 2-1 to press it on to the top of the slide.

The rear end of the slide 1 is guided by a forked bracket 25, mounted on the strap 1', and by a pin 26 which is carried by the bracket and passes through a slot in the slide.

In order, to enable if 'desired, each barrel to be fired by its appropriate trigger, there is provided a catch 27 which, when moved to its operative position engages a beak 0n the slide and prevents the slide from moving forward when a trigger is pulled; the catch 27 is pivotally mounted at 28 and is provided with a tooth 29 which enters a jaw 30 formed on an operating thumb piece 31, see Figures 8 and 9. I

In operation, assuming that the slide retaining catch 27 has been set in its inoperative position, the slide 1 is moved rearwardly when the gun is broken,'by the barrel locking bolt 7 engaging the forked lever 3 and the slide 1 is'held cocked by the spring pawl 12 engaging the front tooth 13 on the top of the slide (see Figure 1) Either bar-f relcan then be fired by pulling the appropriate trigger (which operates its sear, the sears-being indicated at 32). When this is done, the trigger blade is raised, moving with it the spring pressed pawl 12 which is thereby raised out of engagement with the front tooth 13 on the top of the slide (see Figure 2) the slide is moved forwardly by the forked lever 3 until the pin 2 on the slide 1 comes into contact with the rear projection or stop 19 formed on the bottom of the slot 18 in the trigger blade. When the trigger is released, the slide is moved forward until arrested by the pawl engaging the rear tooth 14 on the top of the slide (see Figure When the gun recoils, an involuntary pull is given by the operator, and this raises the trigger blade and consequently the pawl 12 out of engagement with the rear tooth 14 on the slide which latter moves forward until arrested by the forward projection 20 on the bottom of the slot in the trigger blade (see Figure 4:) The trigger then returns to its normal position (see Figure 5) the pro jection moves out of the path of the pin 2 on the slide 1, thus allowing the slide to move forwardly until the lugs 22 on the lever 23 engage the recesses 21 on the rear of the trigger blades, and when the operator pulls the trigger again, the said lugs 22'raise both trigger blades, thus firing the second barrel.

115 it be desired to use the gun as an ordinary double barrel gun, the slide retaining catch 27 is moved so as to hold the slide 1 in its rear position when the gun is broken.

What I claim, is

1. In a double barrel gun, the combination of two triggers, a sliding member, means for cooking the sliding member by the breaking ofthe gun, means on the member for coupling the triggers together, twoteeth spaced apart on the member in the direction from as the triggers are actuated firstly to fire the first barrel and then due to involuntary pull.

In testimony that I claim the foregoing as my invention I have signed my name this 18th day of May, 1931.

of movement of the sliding member, a pawl,

adapted to engage the teeth, an abutment on the sliding member and a pairof abutments which are spaced apart on each trigger in the direction or movement of the member and are adapted to co-operate with the abutment on the sliding member, the pawl co-operating with one tooth, to hold the sliding member in cocked position until one trigger is actuated to fire its own barrel whereupon the sliding member is permitted to move towards its coupling position in limited steps determined by the abutments and pawl which are brought into operation successively as the trigger is actuated, released and against actuated due to involuntary pull and released, the sliding member then being permitted to move into coupling position to enable either trigger 'to fire the remaining barrel.

2. A double barrel gun as claimed in claim 1 in which the abutments 011 the triggers are formed by a slot in each trigger having a pair of cusps constituting the abutments which co-operate withlugs on the sliding member. v V

3. A double barrel gun as claimed in claim 1 in which the sliding member is provided with a transverse pin which enters a slot in each trigger to couple them together.

4:. In a double barrel gun, the combination of two triggers, a movable member which is cocked by the breaking of the gun and is adapted to couple the triggers together, and

a delay action, for preventing the coupling from being effected until after the involuntary pull due to the firing of the first barrel has taken place, comprising a detaining mem'- ber, detaining abutments on each trigger and abutments on the movable member which successively co-operate with the detaining member and the detaining abutments on the triggers and are successively released there-
